Re-fix scaling when rendering a specific element by id

This is a modification of 14fa4591eb34a35cf3d485fd901e3f1e2caa7770

That patch corrected the handling of the view box when rendering an
entire SVG document. However, contrary to intention stated in the
comment of that patch, it turns out that the new viewbox handling code
path can be taken also for the case of rendering only a single element
by id. Instead, we want to keep the original behavior where the
element's origin bounds are transformed to fit into the user requested
target bounds, allowing non-proportional scaling.

Since the render-single-element case is easily and uniqely
identifiable by the sourceRect parameter being non-null, just add an
explicit check for that to the code path branching.
